Proof of principle for nucleon polarization measurement at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +754
A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using events at BESIII, the…
Monitoring the daily variation of Sun-Earth magnetic fields using galactic cosmic rays
The LHAASO Collaboration, C. W. Jiang, Y. Yang
The interplanetary magnetic field (IMF) between the Sun and Earth is an extension of the solar magnetic field carried by the solar wind into interplanetary space. Monitoring variat…
Discovery of a new -ray source LHAASO J0341+5258 with emission up to 200TeV
The LHAASO Collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a new unidentified extended -ray source in the Galactic plane named LHAASO J0341+5258 with a pre-trial significance of 8.2 standard deviations above…
Discovery of the Ultra-high energy gamma-ray source LHAASO J2108+5157
The LHAASO collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a UHE gamma-ray source, LHAASO J2108+5157, by analyzing the LHAASO-KM2A data of 308.33 live days. Significant excess of gamma-ray induced showers is obse…
Detection of very high-energy gamma-ray emission from the radio galaxy M87 with LHAASO
Zhen Cao, F. Aharonian, Axikegu +292
The nearby radio galaxy M87 is a very-high-energy (VHE) gamma-ray emitter established by observations with ground-based gamma-ray detectors. Here we report the long-term monitoring…
Observation of the singly Cabibbo suppressed decay and evidence for
BESIII Collaboration, M. Ablikim, M. N. Achasov +657
By analyzing a data sample of collisions with center-of-mass energy ~GeV, corresponding to an integrated luminosity of collected with t…
